    • The smoke generator produces smoke from combustible matter, such as sawdust or particulated wood, under a controlled set of smoke generation parameters which can be varied over a range of operating set-points. The pyrolysis and partial combustion phases of smoke generation are physically separated and are independently controlled. A controlled rate of sawdust or other combustible matter is fed into an air-excluded pyrolysis chamber in which the pyrolysis temperature is controlled by means of an adjustable power supply to a heating element in the pyrolysis chamber. The ash remaining after pyrolysis of the combustible matter is continuously removed from the pyrolysis chamber. Pyrolytic gases generated by thermal destruction of combustible matter in the pyrolysis chamber are removed to a second chamber where a controlled rate of air is injected with the hot pyrolytic gases to achieve a desired level of partial combustion. The air supply is metered and is preheated to a desired temperature by an adjustable power heater element prior to injection into the partial combustion chamber. Thus, a concentrated smoke at elevated temperature is produced in the partial combustion chamber. A heat exchange apparatus is attached to the smoke outlet from the smoke generator to cool the hot smoke gases by mechanical heat exchange rather than by dilution with ambient room temperature air. Cooling the concentrated smoke gases to ambient temperature by this means quenches further combustion reactions of the concentrated smoke which can then be delivered and utilized in a food smoking kiln.

    • PROBLEM TO BE SOLVED: To prevent contamination of surroundings by carbonizing waste, and hence eliminate the need of a high flue, reduce the fuel cost, shorten processing time, reduce the manufacturing cost, miniaturize an apparatus, and simplify refuse processing. SOLUTION: When a vaporization combustion chamber 1 is heated with a heating burner 14, waste is vaporized and combusted to produce gas which is raised and enters a combustion chamber 18 together with waste gas. Thereupon, air from a combustion blower 24 is sucked into a waste gas rising pipe 13a from an air inflow hole 28, and the 28, and the gas from the vaporization combustion chamber 1 passing through an inside gas rising pipe 1a surrounded by the waste gas rising pipe 13a is sucked smoothly into a smokestack part 21 in the combustion chamber 18 without staying by suction force caused by the joining of the air. Both gases are completely combusted in the smokestack part 21 with the aid of fire of the combustion burner 23, and then enters the combustion chamber 18 and passes throug a catalyst 27a from an exhaust outlet 27 whereby it is deodorized and exhausted to the outside.
